Hawaiian Ching, who plays for Houston Dynamo, featured as a second half substitute in Tuesday's 4-2 friendly defeat to the Czech Republic.

The other six players to miss out from Bradley's provisional 30-man roster were defenders Chad Marshall and Heath Pearce, midfielders Alejandro Bedoya, Sacha Kljestan and Robbie Rogers and forward Eddie Johnson.

Central defender Oguchi Onyewu, who made a tentative return against the Czechs after seven months out following a knee operation, was included.

The United States will face England, Slovenia and Algeria in World Cup Group C. Before then, Bradley's team will face Turkey in Philadelphia on Saturday and Australia in Roodepoort, South Africa, on June 5.
